Abstract (en)
[origin: EP2803698A1] Provided are a rubber composition for conveyor belts that satisfies both cutting resistance and production workability without worsening the wear resistance thereof, a rubber for conveyor belt covers using the rubber composition, and a conveyor belt using the rubber composition. Concretely provided are a rubber composition for conveyor belts containing (A) a rubber component that contains a styrene-butadiene rubber mixture having a mean styrene content of from 28 to 35% by mass, which contains one or more types of styrene-butadiene rubber having a styrene content of from 20 to 25% by mass and one or more types of styrene-butadiene rubber having a styrene content of from more than 25 to 50% by mass, and at least one selected from butadiene rubber and natural rubber in a specific ratio, (B) silica, (C) resin, and (D) specific carbon black in a specific ratio; a rubber for conveyor belt covers, formed by using the rubber composition; and a conveyor belt cover provided by using the rubber composition.
